So, i foudn this puzzle that hasn't been played too many times. I got it correct, but it was by accident. I'm n to really sure how its winning but the computer claims it is. So if someone could explain it I'd really appreciate it.
Puzzle:
lichess.org/training/Jx3bPThat’s a very good question. Even stockfish couldn’t find much of an advantage after several moves
Yeah, its a bit of a weird puzzle.
White does not win any material, but after R4b6+ blacks king is stuck on the a-file forever and he needs to place his rooks quite passively to prevent mate.
So I guess the computer is right to like whites position, but I don't think this really qualifies as a puzzle, you just play some good moves...
This is one of these engine-generated "puzzles" that shouldn't be in the pool.
I just tried it myself and failed, then used the engine and the eval is +6, but the suggested moves are just repetitions. Increasing depth exhibits a crazy line to win the knight.
41. Rb7+ Ka5 42. Rcb4 Rf4 43. R4b6+ is the solution.
After 43. ... Ka5 you can go 44. Bd5 Ne4 45. g3 Rg4 46. Rb2 Nc5 47. Ra7+ Na6 48. Bc6 Rb4 49. Ra2+ Kb6 50. R7xa6+ to win the knight. Now you can ask, why does he have to go 44. ... Ne4? Other moves lead to mate in about 10 moves and the blocking move 44. ... Ra4 loses the knight in another fancy way, that I don't want to write down here (ask Stockfish on depth ~40 to see these lines).
When I do very hard puzzles (3000 level) I had 2350 and just did 600 for fun. Anyways, there are puzzles that u only win +0,5 without taking anything
I think the reason why the final position is winning is the position of black king... I spent like 10 minutes on the 3rd move and could not find a concrete way to win but no other moves made any sense to me - trading rooks is poitless and after R7b6+ Ka7 R7+ Ka8 I could not find any meaninigful threats. The 3rd move just screams to be played. Black has no active plan, has to defend against mating ideas and (if it was a real game) white can make perpetual anytime he wants... It just had to be the right move. After playing with the engine black has to eventually give up rook for bishop with winng endgame for white. For example 4.Bd5 Ra4 5.Rb1 Ka6 6.Rc7 fxg2 7.Bc4+ Rxc4 8.Rxc4
I was just guessing aswell, but I think you can get it correctly by just playing natural. I checked with the engine and after a series of moves, white is able to play gxf3 without black taking back and black will be in Zugzwang. One Rook on A4 covering the A file and denying the C4 square of the Bishop. One Rook on D8 covering the d pawn and the A8 square. The d pawn is blocked by the Bishop, H pawn defending the Knight and the Knight being dominated by Bishop/Rook/King.
